About Short Hundredweights
A short hundredweight (cwt, US cwt) equals exactly 100 pounds or approximately 45.359 kg. Used primarily in the United States for commodity trading, it represents the practical 'hundred-pound' unit for measuring coal, agricultural produce, livestock feed, and industrial materials. Commodity markets for cattle, hogs, and grain in the US price their products per hundredweight ($/cwt or $/100 lb). Steel and non-ferrous metal quotations in North America are commonly expressed in dollars per short hundredweight. The 'short' modifier distinguishes it from the UK long hundredweight (112 lb).
About Electronvolt mass
In particle physics, mass and energy are interchangeable via Einstein's E = mc². The electronvolt (eV) as a mass unit equals the mass equivalent of 1 eV of energy (approximately 1.783 × 10⁻³⁶ kg). Particle masses at the subatomic scale are routinely expressed in MeV/c² or GeV/c² - the proton mass is 938.3 MeV/c², and the electron is 0.511 MeV/c². The Higgs boson, discovered at CERN in 2012, has a mass of approximately 125.25 GeV/c². This unit is exclusively used in high-energy physics and quantum field theory, where conventional mass units like grams would require impossibly small exponents.
